1 Also known as Occam’s razor, law of parsimony, law of economy, and principle of simplicity. The term “Ockham’s razor” references William of Ockham, a 14th century Franciscan friar and logician who purportedly made abundant use of the principle. The principle does not actually appear in any of his extant writings and, in truth, little is known about either the origin of the principle or its originator. See, for example, “The Myth of Occam’s Razor” by W. M. Thorburn, Mind, 1918, vol. 27, p. 345–353.
